PCT No. PCT/CH96/00350 Sec. 371 Date Apr. 3, 1998 Sec. 102(e) Date Apr. 3, 1998 PCT Filed Oct. 4, 1996 PCT Pub. No. WO97/13986 PCT Pub. Date Apr. 17, 1997A rotordynamic machine for the forwarding of a fluid, such as a turbomachine (2) or a centrifugal pump, has at least one drive and bearing apparatus (1) which is designed as an electrical machine with a stator and with a magnetically journalled rotor (4a). Electrical windings (15, 16) produce the required torque and the magnetic bearing force and are arranged together in the stator. The rotor (4a) forms a section of the shaft (4) of the turbomachine (2) and a control apparatus (7) and excites the two windings (15, 16). A magnetic suspension force acting on the rotor (4a) is produced with the first winding (16) in order to hold the shaft (4) in the radial direction without contact. The torque acting on the rotor (4a) is produced with the second winding (15). |
